    Hello,

    My explorer root directories are based upon a user managed config file. It can happen that the directory is incorrect/removed whatever. this creates an ugly error;
    How can I show a userfriendly message that the directory does not exist?
    And/or how can I force the explorer to show an empty directory?

    I tried
    return new DirectoryItem("Invalid directory", string.Empty, "/", "tag", PathPermissions.Read, null, null);
    but that shows the root directory.

    Any ideas?
    Thanks

    Hello Marco,

    I recommend you to perform a check in the Page Load event and if a directory does not exists then clear the paths set to RadFileExplorer and then set only the ones that really exists. :
    • You can clear the RadFileExplorer's pats by clearing the TreeView's nodes. This will cause the new  paths (set in the next step) to be populated:
      RadFileExplorer1.TreeView.Nodes.Clear();
    • Then set the paths again, avoiding the incorrect ones
    • Show a message to the client using Scriptmanager.RegisterStartupScrip method

    I hope this helps.

    I didn't think of that.
    I'll give it a try.
    Thanks
